There’s some relief for businesses and school districts that have criticized recent electric rate hikes.

The Public Utilities Commission of Ohio on Thursday rejected a rate structuring formula instituted this year by Columbus-based American Electric Power. The PUCO ordered AEP to return its rates to levels similar to those in place in December.

These rates will remain in place until a new rate plan is adopted.

The PUCO chairman says the decision allows regulators to start over and ensure they have a complete picture of any rate proposal to balance the interests of customers and the utility.
